Chrysanthemum plant named ‘Zanmutumen’

ABSTRACT

A  chrysanthemum  plant named ‘Zanmutumen’ characterized by its medium sized two-tone orange blooms with dark centers and prolific branching; natural season flowering date September 10, blooming for a period of 5 weeks.

Botanical designation: Chrysanthemum x morifolium Ramat.

Cultivar denomination: ‘Zanmutumen’.

RELATED CULTIVARS

This new plant cultivar ‘Zanmutumen’ is of the botanical classificationChrysanthemum x morifolium Ramat.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofchrysanthemum plant, botanically known as Chrysanthemum x morifoliumRamat., commercially known as a garden mum, and hereinafter referred toby the cultivar denomination ‘Zanmutumen’. ‘Zanmutumen’ is a product ofa breeding and selection program for outdoor pot mums (garden mums)which had the objective of creating new cultivars with a double typeinflorescence, a natural season flowering date around September 10 (week37), blooming for a period of 5 weeks. ‘Zanmutumen’ is a seedlingresulting from a cross of the female parent 54477 (unpatented) with themale parent 15123 (unpatented). Plants of the new cultivar ‘Zanmutumen’differ from plants of the female parent in plant shape: plants of theseedling are more round than plants of the female parent, which show amore spreading habit. Plants of the new cultivar ‘Zanmutumen’ differfrom plants of the male parent in the following characteristics: (1)Plant shape, and (2) Inflorescence color. (1) Plants of the seedling aremore round than plants of the male parent, which are more erect. (2)Inflorescences of the seedling are orange, while those of the maleparent are more bronze.

The new and distinct cultivar was discovered and selected as a floweringplant by Sjoukje Heimovaara on a cultivated field in Rijsenhout, TheNetherlands in September 2013. The first act of asexual production of‘Zanmutumen’ was accomplished when vegetative cuttings from the initialselection were propagated further in a controlled environment in October2013, in Rijsenhout, the Netherlands. In summer, about 6-8 days areneeded to initiate roots in cuttings of the new cultivar, after another5 days rooted plants are formed. The new cultivar has been found toretain its distinctive characteristics through successive propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum (ofabout 17 weeks) is shown in the accompanying drawings, the color beingas nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the new cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants in theperiod of 15 to 21 weeks of age grown outdoor in Rijsenhout, theNetherlands, under natural day length and temperature and planted inweek 21 in 2018, receiving drip irrigation. The natural blooming date ofthis crop was September 10. The average height of the plants was 37 cm.No growth retardants were used. No tests were done on disease or insectresistance or susceptibility. No tests were done on cold or droughttolerance. This new variety produces medium sized two-tone orange bloomswith dark centers blooming for a period of 5 weeks.

From the cultivars known to the inventor the most similar existingcultivar in comparison to ‘Zanmutumen’ is ‘Zanmucopper’ (U.S. Plant Pat.No. 29,449). When ‘Zanmucopper’ and ‘Zanmutumen’ are compared thefollowing difference is noticed: plants of ‘Zanmucopper’ flower later inthe season than those of ‘Zanmumtumen’.

The following is a description of the plant and characteristics thatdistinguish ‘Zanmutumen’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances.
